Long story short: I have eye’d this GPU so I am thinking about it.
Even if I end up not buying it, I still want to have an idea of how it would even just work with Linux.
The GPU is from 2016.
It has “Baffin” graphics, meaning that _it has GCN 4 gen_, this one in particular supporting Vulkan 1.4 .
It trades blows with the GT 1030, but there are no direct comparisons between the two done by anyone, really.
Comparing the RX 460 isn’t the same because it’s just a different GPU.
Even if “the numbers” are simply higher for the 4100 it’s not a given that it may perform better in games,
but at least the higher Vram (and BUS width) should help with higher resolutions and textures, and maybe with Proton.
Conclusion:
This GPU should not have any compatibility or functional problems with Linux.
Having a Workstation GPU for a personal PC is not really a problem, just like “le oldie GT 210 in 2012” and stuff like that (discretion: only the GTX 750+ti GPUs can properly support Wayland, all the others and the even older ones must use Nouveau), or even just integrated graphics, as long as the most graphically intensive things one does are Office Presentations and YouTube.
Workstation GPUs can and do game, and in some cases they also have a special place “in the market”.
Small Form Factor PCs need Low profile GPUs; and even if it’s not a SFF and a LP-GPU, Workstation cards usually occupy only 1 slot, so one can fill more under the GPU, or the GPU doesn’t kiss the bottom of the case or the PSU’s head.
